Do you mean that the games don't work after you extract the files and remove (or leave there) the original archives? If that's the case I suggest this simple test, comment the 2 commands executed "if PACKED & 2" so that you will extract only the non-compressed files and check if the ga...

unfortunately the problem in this case was a longlong that was set as long (fixed in the current script) and the need of allocating lot of memory for unpacking the archive. Basically the whole archive is packed as an unique compressed stream so the memory-to-memory feature of quickbms requires to al...

except for the encryption, it's the same format of Sin Punishment 2.

The following is the quickbms script to extract the files:

@Ekey
thanks for the key

Luckily the update was quite simple and didn't require debugging, just added the new key and ttarch_chunks_b set to 1:

I'm checking the file and the bms script, looks like OFFSET is a 16bit field but it's not clear what's different in the lzma algorithm.

I have improved the PHP script that lists the BMS scripts located in the "others" folder of the QuickBMS website: http://aluigi.org/quickbms.htm#others As you can see now you have also the title of the script and some parts of the idstring, comtype, encryption, filexor and filerot commands...

cool, script updated for supporting the handling of both meta and paz archives depending by what the user choice :)

the new version of quickbms is out: http://quickbms.aluigi.org regarding the paz archives I used those posted by ehnoah, and if you sum the offset and size of the last file you reach the end of archive without unused bytes at the end. maybe it's an old archive and they added the string tables in the...

I checked pad00001.paz (and I bet that 2.paz is the same), there is no free space for string tables.
it contains only the files content

I have checked one of the PAZ file but there is no names table there, just the header, the entries and the content of the files without "empty spaces".

I guess I have finished the script but I have not tested it because I don't have all the files: http://aluigi.org/papers/bms/others/blackdesert.bms You need the new version of quickbms for using it because I have added the new compression algorithm, I will release the new version in the next hours N...

judging the pseudocode it looks lzo1x

here I have everything except the number of PAZ archive (pPAZFileNum) where is located the file assigned to the filename. Do we have a full understanding of the index table? This is what I have for the files linked in the first posts (0 meta and 1/2 paz): get HASH long get FOLDER_NUM long # 48c 48c ...

thanks a lot. I have tried the pseudo code of the sub_41C680 function (with some modification to compile it) and it works, while Decompress doesn't seem stable but after all it's not strictly necessary. so the only missing thing is the assigning of the filenames to the files, that Index table (the o...
